Permit me to express my appreciation for a Post editorial that brought to readers' attention the plight of the Kashmiris and the increasing resort to force by India {"Gunfire in Kashmir," Aug. 27}.

As The Post has rightly pointed out, "India has firmly closed Kashmir to the press" thus erecting a cordon sanitaire around the valley to conceal the repression in the Indian-held Kashmir. It is a travesty of truth to apportion blame on "Moslems in Pakistan" for fomenting the crises because the uprising is purely indigenous in nature. The root cause is easy to determine. It is the denial to the Kashmiris of their right to self-determination in a free and impartial plebiscite, as agreed to by Pakistan and India on the basis of the relevant U.N. resolutions and in the spirit of the Simla Accord. This has not been possible because of India's refusal to honor its own solemn pledges to the U.N.

Let me also correct one misconception about the recent political change in Pakistan. The action by the president to dissolve the National Assembly was taken in accordance with the powers conferred on him under the Constitution of Pakistan. To attribute any motive in this case to the military is unfounded.

The Post's editorial ''Gunfire in Kashimir'' erroneously states that ''India has firmly closed Kashmir to the press.''

Kashmir is fully open to journalists, both Indian and foreign. Foreign journalists, including The Post's own correspondent, have been regularly visiting Kashmir and filing stories.
